Miley Cyrus' Drastic New Hairdo is a Bob

The evolution of the pop star’s new image continues with this latest look, which she debuted at the 24th Annual KROQ Almost Acoustic Christmas Festival in LA on the 7th.

To weather the cold, Miley was clad in head-to-toe black—a turtleneck and oversized coat—and really put the focus on her new head of hair.

It’s definitely a wig. While it appears Miley can do and get away with anything these days, she’s still at the mercy of natural hair growth and there’s no way her infamously shaved pixie could’ve filled out that fast.

Miley’s look was toned down in comparison to just 24 hours before, when she performed at the KIIS FM’s 2013 Jingle Ball in a red two-piece, twerking on Santa Claus' lap.

As the sun starts to set on 2013, it’s clear that Miley’s still full of surprises.
